The clearout continues! I had meant to get this one sorted out and working but never got round to it and probably will not now. So if anyone is interested it is up for £100 plus p&p.
It is in I would say very good physical condition - just the white Sinclair rubbing off. I will post some more photos taken in the daylight tomorrow.
Unfortunately it doesn’t work - it gets to the (C) Sinclair prompt more often than not but then the picture goes blocky. RAM issue maybe?
Regardless I would not attempt to fix one of these myself - not enough around to risk one (only 15,000 made of the issue one I have been told) and don’t really have the cash to spend when I have a working one. It may be an easy fix to those who know but that is not me.
